IMPROVEMENT lN DOG-POWERS.

Specification forming part of Letters Patent No. 220,603, dated October14, 1879; application filed May 31, 1879.

reference marked thereon.

Figure l of the drawings is a representation of a side elevation of mydog-power. Fig. 2 is a detail view of the lever and bar by which thedasher-rod is connected to the power, and Fig. 3 is a detail view of theupper end of the 'dasher-rod.

This invention has relation to dog-powers, and consists in theimprovements in the construction of the same hereinafter fully describedand particularly pointed out in the claim.

A represents belts or chains of suitable form and tensile strength,which pass aroundthe pulleys B and (J. D are round pieces of woodproperly attached to these belts or chains by screws or bolts, in such amanner that they will be in contact on their adjacent sides, and by thusimpinging against each other hold the endless-belt structure in aslightly convex position in that part intended for the tread of theanimal at the point designated by the letter E.

His a bar attached to the lever K by the slot k and between the rollersof the dasher K. The dasher is provided with the anti-friction rollers70 which work upon the upper and lower sides of the reduced portion oftheleverK.

M is a brake which is applied to the flywheel and retained in anydesired position by the button m, which works lightly and has the notchm, in which the handle of the brakelever rests, and which serves toretain the brake-lever at any part of the sweep of the button.

By my invention I avoid all friction which has attended the formerconstruction, as the tread is self-supporting, having no bearingsbetween the end rollers.

I do not wish to confine myself to round pieces, as flat square-edgedpieces, slightly chamfered to receive the animals feet, would clearly doas well, and be no departure from my invention.

Also, by means of the bar H, I provide for a vertical upward anddownward motion for the dasher, and avoid the horizontal motionattending the common form of attaching dash ers and similar devices to aworking -lever or walking-beam.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

In a dog-power for a churn, the lever K, pro vided with the pivot k, incombination with the bar H, pitman l, and dasher K, provided with theanti-friction rollers W, as and for the purposes substantially as setforth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

ELIJAH GLENDILLEN.
